Merge VMware and NetApp VM information

I have a report that lists information for virtual machines in vCenter:

get-vm | select name, numcpu, memorygb, provisionedspacegb

However, each VM is also connecting to an iSCSI LUN on NetApp at the OS level using an iSCSI initiator

I need to figure out the size of the iSCSI LUN that this VM connects to at the OS level, then merge that with my existing columns.

When I'm done I need to have a report like this:

I've got the Netapp PowerShell toolkit installed

NetApp PowerShell Toolkit 4.7 released! - NetApp Community

Has anyone successfully done something like this - taken VM data from vCenter and data from NetApp, and combined them into a single report that pulls data both from vCenter and from NetApp?
